[mcstas-users] Fwd: neutron focusing optics

[Emmanuel FARHI]

Hello dear fellow McStas simulators

here is a post-doc position for the McStas amateurs. The proposed 
mirrors, which have been fabricated, can be used for SANS machines, and 
are built from concentric cylindrical mirrors.

If you are interested, please contact directly the proposers below, and 
I'll also be able to tell you about new complex geometry features in 
McStas...

Emmanuel FARHI.

Post‐doctoral position in neutron optics research at the MIT Nuclear 
Reactor Laboratory.

MIT has a post‐doctoral position available in neutron optics research. 
Experience and interest in
neutron, x‐ray, or light optics and instrumentation is an important 
prerequisite for this position. MIT has
a long history of groundbreaking research in neutron science and 
currently several faculty members are
involved in both applications of neutron scattering and neutron 
instrumentation. Recently neutron
beam focusing has been demonstrated by axisymmetric mirror systems based 
on a pair of mirrors
consisting of a confocal ellipsoid and hyperboloid. Such a system, known 
as a Wolter mirror
configuration, is commonly used in x‐ray telescopes. This position would 
emphasize the development of
these novel optics for neutron applications such as SANS and imaging, 
with special interest in improving
the performance of SNS instruments.
The successful candidate will design and optimize focusing optics for 
particular neutron instruments,
using both ray‐tracing simulations and measurements of test mirrors. The 
design includes modeling and
measurements the effects of figure errors and surface roughness. In 
parallel, the opportunity will exist
to engage in an independent neutron research in condensed matter and 
materials science. The MIT
Nuclear Reactor Laboratory has a new neutron spectrometer with an optics 
test station, which is used in
this research program, along with visits to large user facilities. This 
project is conducted in collaboration
with the x‐ray optics group at NASA and with scientists at the 
Spallation Neutron Source.
